Overall rank by patents
#10,752
of 50,000 tracked assignees
USPTO PatentsView assignee record - 29 granted patents across 2 technology areas, recorded in grant years 2019–2025. Grant-trend analysis is cross-referenced to USPTO Patent Public Search; it does not measure application filings, current R&D, or legal strength. Primary class: A45F (TRAVELLING OR CAMP EQUIPMENT: SACKS OR PACKS CARRIED ON THE BODY).
The verdict
According to USPTO PatentsView, Shenzhen ranks #10,752 of 50,000 tracked US assignees by granted-patent volume, with 29 patents across 2 technology areas.
Shenzhen Kean Silicone Product Co., Ltd. has been granted 29 US utility patents between 2019 and 2025, placing Shenzhen Kean Silicone Product Co., Ltd. at #10,752 of 50,000 across all assignees tracked by PlainPatent. This portfolio spans 2 distinct Cooperative Patent Classification (CPC) subclasses, averaging 1.6 claims per patent with primary concentration in A45F (TRAVELLING OR CAMP EQUIPMENT: SACKS OR PACKS CARRIED ON THE BODY). As a Foreign Corporation, Shenzhen Kean Silicone Product Co., Ltd. is one of the more focused assignees in the PatentsView dataset. By volume, Shenzhen sits between Selecta Biosciences, Inc. (29 patents, rank #10,762) and Siliconintervention Inc. (29 patents, rank #10,770) - the closest US assignees by grant volume. The composite Innovation Score of 22.3/100 blends portfolio volume, grant velocity, technology breadth, and claim depth into a single comparable measure drawn directly from USPTO PatentsView records.
Grant cadence records the difference between two grant-year windows. Between 2020 and 2024 the company received 24 grants, compared with 3 in the 2015–2019 window, a +700% shift in five-year grant velocity. Both windows cover five complete grant years; the latest PatentsView year is a partial release and is excluded from this comparison, though it still appears in the yearly table and chart below. Grant timing can lag the related application by years, so this comparison does not establish current R&D spending, strategic intent, or a company’s application activity. The Foreign Corporation classification provides context for the assignee record, not a conclusion about its business strategy.
Claim depth and technology breadth describe this aggregate record. Shenzhen Kean Silicone Product Co., Ltd.'s 1.6 average claims per patent is an average count, not a measure of claim scope, legal strength, enforceability, or design-around risk. The record spans 2 CPC subclasses. Combined with portfolio volume, these figures let readers compare the documented grant records of assignees in similar technology classes.

How to use this portfolio
Shenzhen's 29 grants land it in the top 90% by Innovation Score, but volume alone doesn't tell you where the strength sits.
Patent counts and the Innovation Score measure patenting activity, not commercial success or the legal strength of any patent. Many patents are filed defensively. Verify the status of an individual patent against official USPTO records.
